Nordson EFD Product Safety Statement (continued)
Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components.
Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage.
Halogenated hydrocarbon solvents contain one or more of the following elements.
Element Symbol Prefix
Fluorine F “Fluoro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
Check the Safety Data Sheet (SDS) or contact your material supplier for more information. If you must use
halogenated hydrocarbon solvents, contact your EFD representative for compatible EFD components.
High Pressure Fluids
High pressure uids, unless they are safely contained, are extremely hazardous. Always release uid pressure before
adjusting or servicing high pressure equipment. A jet of high pressure uid can cut like a knife and cause serious
bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning.
Any injury caused by high pressure liquid can be serious. If you are injured or even suspect an injury:
• Go to an emergency room immediately.
• Tell the doctor that you suspect an injection injury.
• Show the doctor the following note.
• Tell the doctor what kind of material you were dispensing.
WARNING
Medical Alert — Airless Spray Wounds: Note to Physician
Injection in the skin is a serious traumatic injury. It is important to treat the injury surgically as soon as possible. Do
not delay treatment to research toxicity. Toxicity is a concern with some exotic coatings injected directly into the
bloodstream.

Testing in Timed Mode
1. Refer to “Testing in Steady Mode” on page 17 to purge your dispensing tip with uid.
2. Change to TIMED mode.
3. Set the time to 000.0250 seconds.
4. Rest the dispense tip on the Dot Standards sheet.
5. Press the foot pedal (or nger switch) to activate the dispense cycle.
NOTE: The pedal only needs to be pressed for a moment. The complete time will run once you activate the
dispense cycle.
6. Changing the time changes the deposit size. If your dot is too small, increase the dispense time to increase
the deposit size. If your dot is too large, decrease the dispense time to decrease the deposit size.
Testing in Teach Mode
1. Refer to “Testing in Steady Mode” on page 17 to purge the dispensing tip with uid.
2. Change to TEACH mode by going to the menu and scrolling to TEACH.
3. Rest the dispense tip on the Dot Standards sheet.
4. Press the foot pedal to establish your dot size. Depressing the foot pedal repeatedly will have a cumulative
effect on the dot size and dispense time.
5. Continue to press the foot pedal until you achieve the correct deposit size.
6. If needed, press CLEAR to start over.
7. Save the dispense time setting you just created by pressing SAVE. This automatically exits TEACH mode and
returns you to TIMED mode.

Helpful Hints
• There are three core variables for setting up the Ultimus high precision uid dispenser: dispense time, pressure,
and vacuum. Adjust just one of these at a time, in small increments, to achieve the correct deposit.
• Another important variable is tip size. Choose the right tip for the deposit type. Remember, smaller tips require
more pressure and more time. Try different tips without changing the time or pressure settings and observe the
results.
• Tapered tips reduce the amount of air pressure needed to dispense thick materials. They also help prevent
drooling at the end of a dispense cycle.
• To ensure smooth uid ow and to make consistent deposits, keep the dispense tip at a 45° angle to the work
surface.
• Use EFD SmoothFlow pistons to make barrel loading, dispensing, and uid handling cleaner, safer, and more
accurate.
If you dispense watery uids and choose not to use EFD pistons, do not increase vacuum pressure rapidly and do
not tip the barrel. Vacuum may pull uid into the adapter hose, or, if the syringe barrel is tipped, uid may ow back
into the dispenser.
CAUTION
• Always use new EFD syringe barrels and tips. Carefully dispose of after use. This procedure ensures maximum
cleanliness, prevents contamination, and provides proper safety.
• Do not completely ll the syringe barrel. For most uids, optimum ll is a maximum 2/3 of the barrel capacity. For
cyanoacrylates or watery uids, optimum ll is 1/2 of the barrel capacity.
Suggestions on Settings
• Avoid high pressure settings with very short time settings (example: 5.5 bar / 80 psi at less than
000.0100seconds). The ideal setup matches air pressure and tip size to produce a “workable” ow rate – no
splashing, but not too slow either – with a time setting that is not extremely low.
• With any uid, always give the air pressure time to do its job. Moderate time and pressure provides the best
results since dispensing pressure remains at its peak for a longer period of time.
• Longer dispense time settings generally provide the highest accuracy. However, in the interest of cost-effective
production, do not use excessively long dispense time settings. Experiment to nd what works best for your
application.

Advanced Features (Memory)
The Ultimus high precision dispenser allows you to store the dispense time, pressure, and vacuum settings for up to
16 different job programs. Programs are saved even with power removed and will remain in storage unless changed
or erased intentionally.
Job programs are identied as Memory 1 through Memory 16.
NOTE: Dispense time is automatically adjusted when you select an individual job program. Settings for pressure and
vacuum are stored and can be displayed but you need to manually adjust the pressure and vacuum regulator knobs
to match the stored settings for these values.
To Save a Job Program
1. From TIMED or TEACH mode, set the dispense time, air pressure, and vacuum settings to create a correct
deposit size. When you are in TEACH mode, press SAVE after you create your settings, then return to TIMED
mode.
2. Press MENU. Use the up / down arrows to scroll to SAVE JOB. Press SELECT.
3. Use the up / down arrows to select the correct job program in which to save these settings (example, Memory1
or Memory 2).
Remember: to prevent accidental data loss, review the contents of each job program before selecting and
storing a new job into memory.
4. Press SAVE. This automatically saves the settings in the job program.
To Work in a Saved Job Program
1. Press MENU. Use the up / down arrows to highlight MEMORY. Press SELECT.
2. Use the up / down arrows to scroll through the individual jobs until you reach the correct Memory number.
3. Press and hold SETTINGS to see the stored pressure and vacuum settings for the job.
Remember: Dispense time automatically adjusts when you select a job program. Releasing the SETTINGS
button displays the current values for pressure and vacuum, not the stored values. To retrieve the stored values,
manually adjust air pressure and vacuum based on the pressure and vacuum shown when you press Settings.
4. Press the foot pedal or nger switch to activate the dispense cycle. The Ultimus will automatically make the
deposit based on the settings in the selected job program.
5. To escape from Memory, press MENU. Then press TIMED to return to the Home screen. At this point, you are
still in the current memory setting for the previous job program, but you are free to change time, pressure, and
vacuum without impacting the stored settings in memory.
